Manual

This manual describes the installation, shows the first steps with the software and gives an overview about the features of WUFI®.

Using a building envelope as an example, it is shown how to create a construction, how to set boundary, surface transfer and initial conditions and finally how to calculate and assess this example.

Guideline for the calculation of extensive green roofs

The “Guideline for the calculation of extensive green roofs” and the requisite material data sets have been developed to allow reliable WUFI® simulations and planning of green coverings, in particular on wood constructions.
These investigations were performed as part of the project

“Ermittlung von Materialeigenschaften und effektiven Übergangsparametern von Dachbegrünungen
zur zuverlässigen Simulation der hygrothermischen Verhältnisse in und unter Gründächern
bei beliebigen Nutzungen und unterschiedlichen Standorten.”

(“Determination of material properties and effective surface transfer parameters of green roof coverings
for the reliable simulation of the hygrothermal conditions in and below green roofs for arbitrary types of use and different locations.”
)

funded by the Research Initiative “Future Building” of the Federal Institute for Research on Building, Urban Affairs and Spatial Development.

Guideline for the calculation of gravel roofs

The “Guideline for the calculation of gravel roofs” and the requisite material data set have been developed on the basis of simulations reproducing investigations and measurements performed on gravel roofs in Holzkirchen, Gräfelfing and Milan.

Guideline for the calculation of pitched roofs

This guideline describes the procedure of the calculation and evaluation of pitched roofs with a vapour retarder applied on the whole interior surface.

Hygrothermal Simulation of ventilated pitched roofs with effective transfer parameters

The study at hand presents the preliminary research results from field trials in which the thermal behavior was investigated on several different ventilated roof constructions. Radiation related parameters will be provided for different roofing situations as well as a method to calculate ventilated roofs by means of hygrothermal simulation using effective surface transfer parameters.

Guideline for the calculation and evaluation of an ETICS with wood fibre insulation

This guideline describes the procedure for calculation and evaluating ETICS with wood fibre insulation according to the specification and criteria of the “Verband Dämmstoffe aus nachwachsenden Rohstoffen e.V.”(vdnr). Criteria based on the experience of manufacturers represented in the vdnr are used to evaluate the moisture in wood fibre insulation materials.
These criteria are guaranteed by the manufacturers named in the guideline for the products intended for this purpose – the guideline is not applicable for other products.

Manual

This manual describes the installation of WUFI® 2D, guides the user through the first steps with the program and provides a short overview of its capabilities.

Calculation Example

This introduction will show you how to model a building component in WUFI® 2D, how to specify boundary, surface transfer and initial conditions, how to perform the calculation and how to analyse the results.

As an example illustrating each step, we will analyse the hygrothermal behavior of a concrete ceiling supported by a brick wall with exterior insulation.

Program Help
The program help of WUFI® 2D is also offered separately for download in the latest version.

Weather file list for Google Earth

This *.KMZ file displays the locations of the weather files registered in WUFI’s database by feeding them to Google Earth (which you must have installed).
Some of these weather files are included with WUFI; the others must be purchased from the respective vendor, but they can then immediately be used for WUFI® calculations, without further configuration.

A click on one of the WUFI® icons will display some information about the respective weather file.

Weather data Holzkirchen 1991

The 1991 weather data measured in Holzkirchen can be considered representative for Holzkirchen climate conditions. They are included in the WUFI® installation packages, but IBP also offers them separately for general purposes.

Material files

Guideline for the import of material data in xml format into WUFI®

User defined material datasets can be exported and imported in WUFI® as an xml file. The following guideline explains how these xml files can be used in WUFI®.

Owners of a valid full version can download new (not yet published) material data in your online shop.
After log in go to “Material data” => “My orders”. Here you will find new material data sets which will be included in WUFI® with the next update.
Users of our free version (Light, ORNL, student licenses) are not able to download additional data sets.
